Texas Instruments CD74HC368M96E4

Overview

CD74HC368M96E4 from Texas Instruments is a high-speed CMOS hex inverting buffer/line driver with three-state outputs, designed for bus interface and data routing in industrial control and instrumentation systems. It features dual independent three-state enables (OE1 controls four channels, OE2 controls two), 6 V max supply voltage, -55°C to +125°C operating range, and 8 ns typical propagation delay at 5 V/15 pF.

For engineers reviewing the CD74HC368M96E4 datasheet, CD74HC368M96E4 pinout, CD74HC368M96E4 application, or CD74HC368M96E4 equivalent, this device is selected for high-current bus driving where logic inversion, wide temperature operation, and low power consumption are required - especially in legacy TTL-compatible digital subsystems requiring CMOS efficiency.

Technical Context

The CD74HC368M96E4 implements six independent inverting buffer gates, each with high-drive capability (±35 mA output current) and three-state control. Its dual enable architecture allows selective activation of two functional groups: Y1–Y4 under OE1, and Y5–Y6 under OE2 - enabling partial bus isolation without full device disable.

As an HC-type device, it operates from 2 V to 6 V with CMOS input thresholds (VIH = 1.5 V min at 2 V, 4.2 V min at 6 V) and delivers rail-to-rail output swing. It exhibits balanced tPLH/tPHL propagation delays and supports up to 15 LSTTL loads per output, making it suitable for driving heavy capacitive buses in mixed-voltage systems.

FAQ

What is the maximum supply voltage for CD74HC368M96E4?

The CD74HC368M96E4 supports a maximum supply voltage of 6 V, with absolute maximum rating at 7 V. Operation above 6 V risks permanent damage. For reliable long-term use, maintain VCC within 2 V to 6 V per recommended operating conditions - validated across -55°C to +125°C.

Does CD74HC368M96E4 support 3.3 V logic systems?

Yes, CD74HC368M96E4 is fully compatible with 3.3 V systems: VIH(min) = 2.1 V and VIL(max) = 1.0 V at VCC = 3.3 V, providing >0.5 V noise margin. Output VOH(min) = 3.17 V and VOL(max) = 0.33 V at IOL = 6 mA ensure robust interfacing with 3.3 V CMOS and TTL loads.

How does the dual enable structure of CD74HC368M96E4 improve bus design?

The CD74HC368M96E4 uses two independent active-low enables: OE1 controls Y1–Y4, OE2 controls Y5–Y6. This allows partial bus isolation - for example, holding Y5–Y6 in high-Z while actively driving Y1–Y4 - reducing contention risk and simplifying arbitration protocols in multi-master systems.

What is the typical propagation delay of CD74HC368M96E4 at 5 V?

At VCC = 5 V, CL = 15 pF, and TA = 25°C, CD74HC368M96E4 exhibits a typical propagation delay (tPLH/tPHL) of 8 ns. Maximum delay is 27 ns over -55°C to +125°C, supporting reliable operation in synchronous bus designs up to 25 MHz.

Is CD74HC368M96E4 RoHS compliant and lead-free?

Yes, CD74HC368M96E4 is RoHS compliant with lead-free terminal finish (NIPDAU). It meets JEDEC J-STD-020 moisture sensitivity Level-1 (unlimited floor life at ≤30°C/60% RH) and is qualified for Pb-free reflow per IPC/JEDEC J-STD-020.
